Specimen Validity Test

From: $0.48

This Specimen Validity Testing device is for checking urine integrity for six different abnormalities before performing a drug test. These abnormalities may be the result of substitute urine or contamination due to the donor abuse. Test for adulterated compounds, dilution and pH levels and more.

Urine Specimen Validity Test.

The Specimen Test is used to identify abnormalities found in a person’s urine sample. These abnormalities may be the result of the donor adding a chemical to mask the outcome.

Specimen Validity Test is a test strip that when used as directed establishes the integrity of human urine. The integrity has to be within standard parameters for a rapid drug test to work correctly. And remember a donor who is trying to cheat their test will do what is needed to pass. Adulterating their sample by substitution or adding adulterants is prevalent practice. Testing can catch it for Oxidants, Specific Gravity, pH, Glutaraldehyde, Nitrites, and Creatinine. These are all included in this test.

The test strips are designed to evaluate a donor’s urine sample comprehensively. Abnormalities found will alert you immediately. Only when the donor’s specimen is balanced and has the correct pH level, specific gravity and their creatinine levels are normal will they pass.

What is adulteration?

Adulteration is the tampering of a urine sample with the intent of altering the test result. The use of adulterants can cause false effects in drug tests by interfering with the screening process and by destroying the drugs present in the urine. Dilution may also be a tactic to produce false negative results.

One of the best ways to test for adulteration is to determine specific urinary characteristics as shown below:

  1. OX – Oxidants: Detects the presence of oxidants.
  2. S.G. – Specific Gravity: Tests for sample dilution.
  3. pH: Tests for the presence of acidic and alkaline adulterants.
  4. GLU – Glutaraldehyde: Tests for the presence of an exogenous aldehyde.
  5. NIT – Nitrites: Detects for commonly used commercial adulterants.
  6. CRE – Creatinine: Detects waste product called creatine present in human urine.

How can a sample be adulterated?

Adulterants placed in urine will cause false negatives either by interfering with the screening process or by eradicating the presence of drugs. Bleach, vinegar, Visine, sodium bicarbonate, sodium nitrite, Drano, soft drinks and hydrogen peroxide are examples of adulterants that can interfere with the drug test.

Why should I check a donor’s urine?

Using a Specimen Validity Test strip is the most effective way to check the urine is normal. Always check otherwise, they win and pass the test. Proficient collector/administrators use a Specimen Tests to beat the cheaters.

Directions for use:

  1. Remove a test strip from the canister. Dip the test strip into the urine specimen and remove immediately.
  2. Blot the test gently on its side to remove excess urine.
    Note:  For consistent results, blot the test strip everytime a new one used.
  3. Read the results at one (1) minute by comparing each pad with the color chart printed on the canister. DO NOT interpret after four (4) minutes.
  4. If the test indicates adulteration, refer to your supervisor or ask the donor to provide a fresh urine sample after a thirty (30) minute wait time.

NIH recommends the use of an Adulteration Test and suggests that it checks for pH and specific gravity for initial and confirmatory tests.
